Quick Answer
For most homeowners: telescopic + modular bars (Model A) are the best type — adjustable to any window, DIY in 15–30 min, from $99, 5-star security rating. Bedrooms need quick-release (Model A/EXIT). Renters with no-drill restrictions should use tension bars as a deterrent only. Fixed welded bars are overkill for residential use and cost 3–5× more.
